  2. 1. ATLAS Calorimetry : Hadronic Calibration Studies

    Author : Karl-Johan Grahn; Bengt Lund-Jensen; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Physics; Fysik;

    Abstract : The ATLAS experiment -- situated at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) in Geneva -- is on schedule to take its first collision data in 2009. Physics topics include finding the Higgs boson, heavy quark physics, and looking for extensions of the standard model such as supersymmetry. READ MORE

  4. 2. Immunological and virologica response to antiretroviral treatment (art) in patients infected with different HIV-1 genetic subtypes

    Author : Ann Atlas; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HIV- 1 genetic subtype; CD4 T cell count; viral load; activation markers; IL-7;

    Abstract : Genetic analyses of different strains of HIV- 1 have shown that isolates can be subdivided into groups, subtypes and circulating recombinant forms. Nine different genetic HIV-1 subtypes have been identified so far, named as A, B, C, D, F, G, H, J and K. READ MORE

  5. 3. Search for Weakly Produced Supersymmetric Particles in the ATLAS Experiment

    Author : Maja Tylmad; Christophe Clément; Barbro Åsman; Patrice Verdier; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ATLAS; ATLAS experiment; supersymmetry; chargino; neutralino; physics analysis; LHC; Large Hadron Collider; fysik; Physics;

    Abstract : The Large Hadron Collider located at CERN is currently the most powerful particle accelerator and ATLAS is an experiment designed to exploit the high energy proton-proton collisions provided by the LHC. It opens a unique window to search for new physics at very high energy, such as supersymmetry, a postulated symmetry between fermions and bosons. READ MORE

  6. 4. Searches for exotic stable massive particles with the ATLAS experiment

    Author : Christian Ohm; David Milstead; Torbjörn Moa; Albert Roeck; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ATLAS; ATLAS experiment; supersymmetry; squark; gluino; stable massive particles; long-lived particles; physics analysis; search analysis; LHC; Large Hadron Collider; fysik; Physics;

    Abstract : This thesis presents two signature-based searches for exotic long-lived particles using experimental data collected by the ATLAS experiment at the Large Hadron Collider (LHC) at CERN. At the LHC, proton-proton collisions take place at the world-record center-of-mass energy of 7 TeV and luminosities of up to  3×1033 cm-2s-1 . READ MORE

  7. 5. Looking for the Charged Higgs Boson : Simulation Studies for the ATLAS Experiment

    Author : Martin Flechl; Tord Ekelöf; Richard Brenner; Kinnunen Ritva; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; charged Higgs; tau; ATLAS; HEP; CERN; LHC; Particle Physics; Grid; Physics; Fysik; högenergifysik; High Energy Physics;

    Abstract : The discovery of a charged Higgs boson (H+) would be an unambiguous sign of physics beyond the Standard Model. This thesis describes preparations for the H+ search with the ATLAS experiment at the Large Hadron Collider at CERN. The H+ discovery potential is evaluated, and tools for H+ searches are developed and refined. READ MORE
